PAN-GRIESING- MACHINE.

Application filed February 9,1925. Serial No. 7,747.

To all whom it may concern.' l

Be it known that l, WILHMM MOLLER, a citizen of the lUnited States,residing at Philadelphia, in the county of Philadelphia a and State ofPennsylvania, have invented certain new and useful improvements inlPan-flreasing Machines, of which the following is a specification.

ll/ly invention relates to pan greasing maio chines and moreparticularly to the mechanism for feeding grease to the brushes.

- The objects are to provide mechanism for feeding grease to brusheswhich may .be manipulated to feed any desired quantityl i of greaseevenly to each of a group ot brushes; which is capable of feeding semy1-fluid as well as liquid grease; which operates only when it is desiredto feed the grease, and which is practically leak-proof.

'lhese objects, and other advantageous ends which will be describedhereinafter, ll attain in the following manner, reference being had tothe accompanying drawings in which- Figure 1 is a fragmentary centralvertical section, partly broken away, of a pan greasing machineembodying my grease feeding mechanism,

Figure 2 a section on line 2-2 of Figure 1,

.Figure 3 an enlarged section on line 3--3 of Figure 1, and

Figure l an enlarged fragmentary section of the discharge end of thefeed tube. v

Referring to the drawings, the pan greaslfl ing machine has a frame 1provided with a compartment 2 in which the actuating mechanism ismounted. A pair of guides 3 are mounted on the sides of the compartmentto slidably support step bearings l which may t@ be adjusted toward orfrom each other by screws 5 mounted in the frame. Vertical hollowspindles 6 are rotatably mounted in the step bearings 4 and each spindlehas a pinion 7 fixed thereto which meshes with a rack 8 operativelyconnected with drive mechanism not shown. A brush 9, fixed to eachspindle, is rotated alternately in opposite direction by the'reciprocating motion of rack 8. The above described mechanism is fullyldisclosed in my Patent No. 1,532,- 256, Apr. 7, 1925.

The mechanismV for feeding grease to brushes 9 includes a feed tube,10,fixed to step bearing'ft at 11 and extending upward through hollowVspindle 6 to within a counter-sunk part l2 at the top of the brushhead. 'lhe top of tube 10 is closed and its upper end has a series ofperipheral discharge openings 13 whereby grease forced through theopenings, will strike the face of counter-sunk part 12 andv be dedectedonto the bristles of the brush." A exible conduit 14 is suitablyconnected to the lower end of each tube and to an outlet nipple 15 of agrease pump 16 mounted in a grease tank 17 located in compartment 2.

lhe grease pump consists of a cylinder head 18, having as many cylindersas there are greasing brushes, inlet check valves 19 at the bottom ofeach cylinder and outlet check valves 20 adjacent the bottom. llachoutlet check valve consists of a flanged nipple 2 1 integral with each4cylinder and having a seat 22 therein against which a ball 23 is heldby a spring 2t secured in place by a fitting 25 screwed into nipple 21.'llhis fitting has a flange 26 engaging the outer side of the tank wallto clamp it against nipple 21. This firmly fastens the pump to the/tankwall. Flange 26 may be lined with a gasket to form a seal againstleakage of grease from the tank. lts an additional means for securingthe pump to the tank, l provide lugs 27 at opposite ends of thelcylinder head and secure them to the tank by screws sealed againstleakage.

A. plunger 28, slidable in each cylinder, is secured to a bar 29connected with a lever 30 by a pin and slot connection 31. liever 30 ispivoted at one end to the tank at 32 and pivotally connected at` theother end with a link 33 pivoted on a rod 3ft slidable through thebottom of compartment 2 and through a bracket 3 5 secured to the frame,

' of spring 39, through rod 34, link 33 and lever 30, to the plungers 28and move them downward to force the grease in the cylinders, throughoutlet check valves 22') -and conduits 14, upward through feed tubes 10and out of opening 13 onto the countersunk part 12 of the brush head,which will deflect the grease onto the bristles. The centrifugal forcecreated by the rotating brushes assists the flow of the grease onto thebristles.

Upon releasing pedal 36, springs 39 Will return the plungers and theirassociated parts to normal position. During this movement, grease fromthe tank will be sucked into the cylinders through the inlet valves 19.Outlet check valves 20 will close immediately after the downwardmovement of the plungers stops. This keeps the feed tubes 104 and theirconduits 14 filled with grease. By having the feed tubes and conduitsalways filled, any grease forced out of the cylinders by plungers 28,will instantaneously cause an equal amount to discharge through holes 13in the upper end of the feed tube.

rlhe grease feeding mechanism above described is practically leak-proof,because the pump and its'valves are mounted in the vgrease tank.Discharge of grease onto the brushes may be eected by a slight movementof the pedal because the conduits 14 and feed tubes 10 are alwaysfilled. The mechanism is capable of feeding semi-Huid grease withpractically the same ease as liquid grease.

While ll have described my invention as taking a particular form, itwill be understood that the various parts may be changed withoutdeparting from the spirit thereof, and hence l do not limit myself tothe precise construction set forth, but consider that l am at liberty tomake such changes and alterations as fairly come within the scope of theappended claims.

Having thus described my invention, what ll claim as new and desire tosecure by Letters Patent is 1. ln a pan greasing machine, a grease tank,a series of hollow spindles, brushes carried b the spindles, means forrotating the spin les, feed tubes extending through the spindles andadapted to discharge 1 grease upon the brushes, a pump having a neaaeeecylinder for each feed tube and adapted to pump greasefrom the greasetank, a flexible conduit connecting each cylinder with a feed tube, andmeans for actuating the pump. f
